Logical systems of categories are the core of philosophy and the starting point of all philosophic theories. The same is true for semiotics and linguistics. The author of this paper attempts to construct the logical systems of categories of the two major schools of modern semiotics and those of several representative linguistic disciplines and describe their development so as to illuminate the philosophical origins of the two schools of semiotics and the philosophical and semiotic origins of those linguistic disciplines and the relationships among them. It is hoped that this study serves as a template for research in the fields of semiotics and linguistics
